Low-Voltage 8-Bit I2C And SMBus I/O Expander With Interrupt Output, Reset, And Config Register

The major benefit of this device is its wide VCC range. It CAN operate from 1.65-V to 5.5-V on the P port side and on the SDA/SCL side. This allows the TCA6408 to Interface with next-generation Microprocessors and Microcontrollers on the SDA/SCL side, where supply levels are dropping down to conserve power. In contrast to the dropping power supplies of Microprocessors and Microcontrollers some PCB components such as LEDs remain at a 5-V power supply. The bidirectional voltage level translation in the TCA6408 is provided through VCCI. VCCI should be connected to the VCC of the external SCL/SDA lines. This indicates the VCC level of the I2C bus to the TCA6408. The voltage level on the P port of the TCA6408 is determined by VCCP. By Texas Instruments
